IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety instructions. Please read and follow all instructions carefully
during installation and operation of the unit. Read this manual thoroughly before attempting to unpack,
install, or operate your UPS.
CAUTION! The UPS must be connected to a grounded AC power outlet with fuse or circuit breaker
protection. DO NOT plug the UPS into an outlet that is not grounded. If you need to de-energize this
equipment, turn off and unplug the UPS.
CAUTION! DO NOT USE FOR MEDICAL OR LIFE SUPPORT EQUIPMENT! CyberPower Systems
does not sell products for life support or medical applications. DO NOT use in any circumstance that
would affect the operation and safety of life support equipment, medical applications, or patient care.
CAUTION! Hazardous live parts inside can be energized by the battery even when the AC input power
is disconnected.
CAUTION! To prevent the risk of fire or electric shock, install in a temperature and humidity controlled
indoor area, free of conductive contaminants. (Please see specifications for acceptable temperature
and humidity range).
CAUTION! To reduce the risk of electric shock, do not remove the cover, except to service the battery.
There are no user serviceable parts inside, except for the battery.
CAUTION! To avoid electrical shock, turn off the unit and unplug it from the AC power source before
servicing the battery or installing a computer component.
CAUTION! DO NOT USE WITH OR NEAR AQUARIUMS! To reduce the risk of fire, do not use with or
near aquariums. Condensation from the aquarium can come in contact with metal electrical contacts
and cause the machine to short out.

OVERVIEW
The PR750ELCD provides automatic voltage regulation for inconsistent utility power. The PR750ELCD
features 405 Joules of surge protection, and provides battery backup during power outages. The
PR750ELCD ensures consistent power to your computer system and its included software will
automatically save your open files and shut down your computer system during a utility power loss.
HOW TO DETERMINE THE POWER REQUIREMENTS OF YOUR
EQUIPMENT
1.Make sure that the total Volt-Amp (VA) requirements of your computer, monitor, and
peripheral equipment does not exceed 750VA.
2.Ensure that the equipment plugged into the battery power-supplied/surge outlets does
not exceed the UPS unit's rated capacity (750VA/675W for PR750ELCD). If the rated unit capacities
are exceeded, an overload condition may occur and cause the UPS unit to shut down or the circuit
breaker to trip.

11. Battery and Surge Protected Outlets
The unit has six battery powered/surge suppression outlets for connected equipment to ensure
temporary uninterrupted operation of your equipment during a power failure. (DO NOT plug a laser
printer, paper shredder, copier, space heater, vacuum, sump pump or other large electrical devices
into the “Battery and Surge Protected Outlets”. The power demands of these devices may overload
and damage the unit.)

HARDWARE INSTALLATION GUIDE
1. Your new UPS may be used immediately upon receipt. However, recharging the battery for at least 8
hours is recommended to ensure that the battery's maximum charge capacity is achieved. Charge
loss may occur during shipping and storage. To recharge the battery, simply leave the unit plugged
into an AC outlet. The unit will charge in both the on and off position.
Note: This UPS is designed with a safety feature to keep the system from being turned on
during shipment. The first time you turn the UPS on, you will need to have it connected to AC
power or it will not power up.
2. If you will use the software, connect the USB cable to the USB port on the UPS.
3. With the UPS unit off and unplugged, connect the computer, monitor, and any externally powered
data storage device (Zip drive, Jazz drive, Tape drive, etc. into the battery power supplied outlets.
DO NOT plug a laser printer, copier, space heater, vacuum, paper shredder or other large electrical
device into the battery power supplied outlets. The power demands of these devices will overload
and possibly damage the unit.
4. Plug the UPS into a 2 pole, 3 wire grounded receptacle (wall outlet). Make sure the wall branch outlet
is protected by a fuse or circuit breaker and does not service equipment with large electrical
demands (e.g. air conditioner, refrigerator, copier, etc. Avoid using extension cords.
5. Depress the power switch to turn the unit on. The power on indicator light will illuminate and the unit
will "beep".
6. If an overload is detected, an audible alarm will sound and the unit will emit one long beep. To
correct this, turn the UPS off and unplug at least one piece of equipment from the battery power
supplied outlets. Wait 10 seconds. Make sure the circuit breaker is depressed and then turn the UPS
on.
7. Your UPS is equipped with an auto-charge feature. When the UPS is plugged into an AC outlet, the
battery will automatically recharge.
8. To maintain optimal battery charge, leave the UPS plugged into an AC outlet at all times.
9. To store your UPS for an extended period, cover it and store with the battery fully charged. Recharge
the battery every three months to ensure battery life.
10. The LCD module is wall-mountable for extended distance control. Follow the steps below for
installation procedure.
a. Remove the LCD module from the front panel.
b. Hang the LCD module on the wall.
c. Replacing the LCD on the UPS - To place the LCD back on the UPS, roll up the LCD cable, return
it to the space between the front panel & battery cover, and replace the LCD.

BATTERY REPLACEMENT
CAUTION! Read and follow the IMPORTANT SAFETY INSTRUCTIONS before servicing the
battery. Service the battery under the supervision of personnel knowledgeable of
batteries and their precautions.
CAUTION! Use only the specified type of battery. See your dealer for replacement batteries.
CAUTION! The battery may present the risk of electrical shock. Do not dispose of batteries in
a fire, as they may explode. Follow all local ordinances regarding proper disposal of batteries.
CAUTION! Do not open or mutilate the batteries. Released electrolyte is harmful to the skin
and eyes and may be toxic.
CAUTION! A battery can present a high risk of short circuit current and electrical shock. Take
the following precautions before replacing the battery:
1. Remove all watches, rings or other metal objects.
2. Only use tools with insulated handles.
3. DO NOT lay tools or other metal parts on top of battery or any battery terminals.
4. Wear rubber gloves and boots.
5. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove source
of ground. CONTACT WITH A GROUNDED BATTERY CAN RESULT IN ELECTRICAL
SHOCK! The likelihood of such shock will be reduced if such grounds are removed during
installation and maintenance (applicable to a UPS and a remote battery supply not having a
grounded circuit)
